Answer:
Step-by-step explanation:
The documentary film "Breaking Boundaries: The Science of Our Planet" highlights several environmental tipping points that have been triggered by human activities, leading to global warming and climate change. These tipping points refer to critical thresholds beyond which irreversible and potentially catastrophic changes can occur in the Earth's system.
One of the most significant human activities that have impacted the Earth's system is the burning of fossil fuels. This has resulted in an increase in carbon dioxide and other greenhouse gases in the atmosphere, leading to rising temperatures and changes in weather patterns. This impacts the atmosphere sphere of influence.
Another human activity that has impacted the Earth's system is deforestation. Trees absorb carbon dioxide and other greenhouse gases, so deforestation results in increased carbon emissions and reduced carbon absorption. This impacts the biosphere sphere of influence.
Human activities such as urbanization and agriculture have also led to changes in the water cycle, with altered precipitation patterns and increased water use, leading to changes in the availability and quality of freshwater resources. This impacts the hydrosphere sphere of influence.
Finally, human activities have also led to the release of pollutants and toxic chemicals into the environment, leading to pollution and degradation of ecosystems, which impacts the geosphere sphere of influence.
All of these human activities have contributed to the environmental tipping points highlighted in the film, leading to global warming and climate change and potentially catastrophic impacts on the Earth's system. It is important that we take immediate and sustained action to address these issues and prevent further damage to the Earth's system.
